Improper Output Handling

Apache Log4j Core is vulnerable to Improper Output Handling. The vulnerability is due to XmlLayout failing to sanitize characters forbidden by the XML 1.0 specification, allowing log messages or MDC values to produce malformed XML or trigger exceptions during logging, which can lead to dropped or...
